Complete the process$\_$scenes function to separate lines in scene$\_$text by

$,$ separate speakers from the beginnings of their speeches $($using regex$),$ and collect the multiline speeches in a single string. Each speaker$-$line pair should be stored in the defaultdict structure set up in the code below. Store each speaker$-$line pair as a list. Process act$\_$scene$\_$texts with process$\_$scenes, and print the first five lines of ACT I, SCENE $1.$ Without changing any preset code, and onnly adding between #code starts here and # code ends here.
